I need a gtk2 entry widget to expand (and hopefully contract too)
so as to always display just the text it contains. It is critical
that all the text be visible, not scroll out of sight. I'm using a
monospace font. Is there some neat way to do this?
I've tried a 'changed' callback which does set_size_request, but
calculating the right value (in a multiplatform environment) seems
very hard. Am I missing something simple?

Hi,
when I have a toolbar with icons, the text labels are of
equal width for all buttons. This means, a long text label
spreads all of the buttons out, purshing some menu items
off the screen.
Hmmmm,
Torsten

this is what i use. it sets the size request for any widget so that it
will be big enough to display the given text. note that its broken for
GtkCombo, which stupidly makes a size request, then takes some of the
space for the arrow/button. i imagine its not been fixed in GTK2.
in the gtkmm list archives there is an equivalent using pango.

What's the desired behavior if the text goes out-of-range in size? For
instance, if you're using a 8x10 monospace font, the window is 400x200,
and the display is 800x600, what should happen if your text exceeds 50x20
or 100x60 chars in size? And if you have something like:
|| label |input area| || (where || is a window edge)
what should happen to the label if 'input area' grows enough to push it off
the screen?

The window should simply expand as far as necessary. The application's main window
is inside a scrolled window, so the user can manually scroll if need be --
(and this is important): manually scroll to see part of the window the scroll bars
tell her are obscured. A *fixed* width gtk_Entry does not provide any visual cue
when some data is obscured.
In practice, the awkwardness of dealing with a data window much wider than
the screen will sharply curtail user's verbosity, so I don't worry too much
about people writing War&Peace in a gtk.Entry. The application provides
other places to enter long multi-line verbiage.

From: "Binoj VB"

Hello all,=20
I have installed the gtk+-2.2 with frame buffer support on Redhat 8.0.
The configuration option used is=20
configure --enable-debug=3Dno --with-gtktarget=3DLinux-fb =
--disable-shadowfb
--disable-module -with-included-loaders=3Dxpm,png,jpeg
I tried to run the test programs in the directory,
Gtk+-2.2.0/tests/testcalendar.=20
The GUI poped up and I am able to use my keyboard to select buttons.
When I take the mouse over the GUI, where ever the mouse pointer is
taken the gui color disappears/ I can see the background(black color). I
feel like the GUI is not getting repainted.=20
How do I solve this problem?? Please help..=20
Thanks and regards,=20

Hello all,
I wrote this in the past, but nobody can help me. So I try again,
because this is for us very important.
In dialogs we use gtk_entry_set_width_chars(GTK_ENTRY(entry),length) and
mono spaced fonts like courier 12 to told the entry the visible lenght.
With Linux all is ok. When we start the application on TRU64 or start
the appl remote to Windows with Exceed the entrys are to long, it means
when length is 6 then in the entry has space for 10 character.
Thanks for any help
